Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing dies, in particular to an automatic correction device for wire drawing dies. Background Art

[0002] When the die core of the wire drawing die is grinding the die hole, the die hole is not round (not absolutely round), causing the steel wire to be deformed in an uneven state. The deformed cross section of the steel wire has uneven deformation, which also causes additional stress on the cross section of the steel wire. Coupled with factors such as changes in the die hole size, the steel wire is twisted or bent, resulting in "messy wire" quality problems.

[0003] Before each operation, the position of the wire drawing die needs to be calibrated. The existing calibration work is done manually, which is time-consuming and increases labor costs. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic correction device for a wire drawing die, which has the effect of improving the efficiency of the correction operation and reducing the expenditure of labor costs.

[0008] In a preferred example, the utility model can be further configured as follows: the distance control component includes a placement shell, the placement shell is arranged on the telescopic rod in the telescope, and an infrared rangefinder is arranged in the placement shell;

[0009] A triangular block is provided on one side of the positioning column facing the infrared rangefinder, and the vertical section of the triangular block is a right triangle;

[0010] The inclined surface of the triangular block always faces the infrared rangefinder.

[0011] In a preferred example, the utility model can be further configured as follows: a PLC controller is provided on one side of the base, and the PLC controller is electrically connected to the telescopic device and the infrared rangefinder.

[0012] In a preferred example, the utility model can be further configured as follows: the vertical section of the triangular block is a right triangle with an acute angle of sixty degrees.

[0013] In a preferred example, the present invention can be further configured as follows: a guide component is further provided between the base and the mold body.

[0014] The utility model can be further configured in a preferred example as follows: the guide assembly includes four sleeves, and the four sleeves are vertically fixed on the top of the base;

[0015] Guide rods are arranged in the four sleeves, and one end of each guide rod located outside the sleeve is fixed to the bottom of the mold body.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-Figure 3 As shown, the utility model discloses an automatic correction device for a wire drawing die, comprising a die body 1. A positioning column 2 is arranged outside the die body 1, and a roller is fixedly arranged on the top of the positioning column 2. A die core is arranged inside the die body 1, and a steel wire passes through the die core and the roller. The position of the positioning column 2 and the position height of the roller are fixed.

[0027] A base 11 is arranged directly below the mold body 1. A guide assembly 5 is arranged between the base 11 and the mold body 1. The guide assembly 5 includes four sleeves 51, and the four sleeves 51 are vertically fixed on the top of the base 11.

[0028] A guide rod 52 is disposed in each of the four sleeves 51, and one end of each guide rod 52 located outside the sleeve 51 is fixed to the bottom of the mold body 1. A plurality of first placement grooves 6 are evenly formed on the inner wall of each sleeve 51, and a rotating rod 61 is disposed in each first placement groove 6. A ball 62 is rotatably sleeved on the outer circumference of the rotating rod 61, and a portion of the ball 62 is located outside the corresponding first placement groove 6, and the ball 62 contacts the corresponding guide rod 52.

[0029] A telescope 12 is provided between the base 11 and the mold body 1. The bottom of the telescope 12 is fixed to the top of the base 11, and the telescopic end of the telescope 12 is connected to the bottom of the mold body 1. The telescope 12 and the positioning column 2 are provided with a distance control component 3, and the distance control component 3 drives the telescopic end of the telescope 12 to move.

[0030] The distance control component 3 includes a placement shell 31, which is arranged on the telescopic rod in the telescopic device 12, and an infrared rangefinder 32 is arranged in the placement shell 31. A triangular block 33 is arranged on the side of the positioning column 2 facing the infrared rangefinder 32, and the vertical section of the triangular block 33 is a right triangle with an acute angle of 60 degrees.

[0031] The inclined surface of the triangular block 33 always faces the infrared rangefinder 32. A PLC controller 4 is disposed on one side of the base 11, and the PLC controller 4 is electrically connected to the telescopic device 12 and the infrared rangefinder 32.

[0032] The implementation principle of the above embodiment is:

[0033] First of all, it should be clear that the predetermined value input into the PLC is recorded as L1, and the value of L1 is the distance length from the infrared rangefinder 32 to a point on the triangular block 33 when the mold body 1 is in the correct position.

[0034] When the height of the mold body 1 changes, the straight-line distance from the infrared rangefinder 32 to the triangle block 33 is L2. At this time, L2 is not equal to L1. The actual difference between L1 and L2 is calculated, and then the length of the other right-angled side of a right-angled triangle is calculated by the trigonometric formula when the length of the other right-angled side is known. This value is recorded as L3, which is the distance that the telescopic device 12 needs to move.

[0035] When L2 is greater than L1, the mold body 1 needs to move downward. When L2 is less than L1, the mold body 1 needs to move upward.

[0036] It is also particularly noted that within the normal deviation range of the position height of the mold body 1 , the transmitting end of the infrared rangefinder 32 is always facing the inclined surface on the triangular block 33 .

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
